[squid-users] how to know how much data was sent

[Yedidia Klein]

hi,

As far as I understand the access log of squid log the bytes that was 
sent from the web server to the browser.
Is there any logs of the amount of data that is sent *from* the browser 
(like file upload via http)

this could help us to understand the B/W needs.

thanks
